Okay I'm finally going to be installing the 02 plug and EFI resistor plug after the 600 mile service and I'm wondering if the bike will require some octane booster. Here in California the best pump gas I can find is 91octane R+M/N. Everything else on the bike will stay stock.
Do the bike a favor. Go pick up a 5 gallon can of Sunoco Race fuel 112 octane, put one gallon of Sunoco to 4 gallons of Super Pump gas and fill the tank with this mix every 4 or five tank fills. My bikes love this mix and thank me for it by running absolutely flawless.
They´ve been adding ever increasing amounts of bio alcohol to standard fuel here in Europe and owners of well tuned four strokes are complaining. So fuel companies are now selling even more expensive `super super´ fuel. So you either have to put up with the bio alcohol ... or pay a lot more for the genuine stuff.
